Fire fighters established that there were high concentration levels of carbon monoxide in the upstairs apartment and followed its path to a freight elevator connected to the downstairs restaurant It’s Time diner.

“They found the same readings downstairs as upstairs,” said KFD Battalion Chief Marc Jefferson. “When we find high readings, we shut off the gas and call the gas company.”

Thursday morning, the It’s Time diner was sealed with yellow warning tape and a note instructing its owners to contact the fire department before opening for the morning.

Jefferson said while KFD cleared the scene after about an hour, the cause of the carbon monoxide leak was not established.

“They’ll need to go in, have a maintenance person come in and check all the appliances before the gas is turned back on,” Jefferson said.

There were no reported injuries or sicknesses associated with the elevated carbon monoxide levels.
